Dimensional Fund Advisors names new co-CEO

In a major management change at Dimensional Fund Advisors, Gerard O'Reilly will become co-CEO of the money manager, replacing Eduardo Repetto, who will leave the position in late September, a spokesman confirmed in an email.

Mr. O'Reilly will also become chief investment officer of the firm, which reported $518 billion in worldwide assets under management as of June 30. He had been co-CIO, sharing the spot with Mr. Repetto, a 17-year veteran at Dimensional.

It is unclear why Mr. Repetto is departing. Efforts to reach him were unsuccessful.
